Hidden services (web based only ? ) are not accessible through Tor Transparent Proxy
Just reading this on the talk list : https://lists.torproject.org/pipermail/tor-talk/2011-May/020323.html
I've seen the same behaviour while trying to access any (web) hidden service through Tor Transparent Proxy function.
I've setup a user , I've configured Tor following this guide : https://trac.torproject.org/projects/tor/wiki/TheOnionRouter/TransparentProxy#Transparentlyanonymizingtrafficforaspecificuser , then launched iceweasel in a separate session for the anonymized user but can't connect to any hidden service.
And dig resolves any hidden service to 127.192.0.x as described in the message linked on the top.
